Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to a compression-resistant elevator guide rail. Background Art

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. Based on the cross-sectional shape, they are divided into three types: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator. Therefore, the guide rails should be selected according to the elevator speed and load. The car guide rails are usually called the main rails and the counterweight guide rails are called the auxiliary rails.

[0003] Announcement No. CN212581282U discloses a pressure-resistant elevator guide rail. By means of the coordinated use of a guide rail body, a first ball, a groove, a buffer layer, a spring, a through hole, a second ball and a support frame, the pressure-resistant elevator guide rail has good pressure resistance, and solves the problem of poor pressure resistance of general elevator guide rails. When the elevator is in use, the pressure and friction on both sides of the guide rail are reduced, and while the service life of the elevator guide rail is increased, the impact of the guide rail on the normal use of the elevator is reduced, further meeting people's current use needs. By providing a guide rail body and a wear-resistant layer, the wear resistance of the guide rail body can be improved, thereby extending the service life of the guide rail body and making people more worry-free when using it. However, the patent still has the following problems in actual use:

[0004] Although the compression-resistant elevator guide rail achieves the purpose of good compression resistance by arranging the guide rail body, the first ball, the groove, the buffer layer, the spring, the through hole, the second ball and the support frame to cooperate with each other, during the long-term use of the guide rail, the impact force will cause the first ball and the second ball to deform. Once the first ball and the second ball are deformed, the smoothness of the guide rail will be affected, thereby causing a certain impact on the guide rail body. In severe cases, the guide rail body will be damaged.

[0005] Therefore, a compression-resistant elevator guide rail is proposed to solve the above-mentioned problems. Utility Model Content
